[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
The fundamental purpose of the utility model design is: a kind of LED display control system that adopts wireless transmission card and wireless receiving card that provides, thereby make whole system have to install simple and easy, without the advantage of line.
Consult shown in Figure 1, the utility model provides a kind of LED display control system that adopts wireless transmission, comprise main frame 10, the transmission card 20 that is connected with main frame 10, a plurality of LED display 40 and a plurality of receiving cards 30 that are connected with a plurality of LED display 40, described transmission card 20 is the wireless transmission card, and described receiving card 30 is the wireless receiving card.Wherein, the utility model also comprises the power supply that is connected with a plurality of receiving cards 30, can provide working power for receiving card 30 like this.In addition, described main frame 10 be computing machine or other equipment demonstration and other data.And in order to facilitate the work that each LED display 40 can be independent, be not subject to the impact of other LED display 40, the quantity of described wireless receiving card 30 is set to equate with the quantity of LED display 40, i.e. wireless receiving card 30 of LED display 40 configurations.And described transmission card 20 and main frame 10 wired connections.
The LED display control system idiographic flow in use of wireless transmission of the present utility model is:
Transmission card 20 Receiving Host 10(PC or miscellaneous equipments) demonstration and other data; Sending card 20 sends data packing compression by wireless towards periphery according to certain protocol format; Wherein, send the concrete form of broadcast packet that adopts of card 20 and send data; Receiving card 30 receives and resolves the information that receives by radio receiver; And then receiving card 30 is delivered to LED display 40 with the valid data that receive and is shown.
Foregoing detailed description is only exemplary description, and those skilled in the art can design various embodiments according to different actual needs in the situation that do not break away from the scope and spirit that the utility model is protected.
